Kondo | January 6, 1998 |
A transmitter which allows to reproduce a high quality and smooth dynamic image on the receiving side even with a transmission medium having a low transmission rate is provided. Background plane data representing a still image of a background image of video and one or more motion plane data representing still images of each of moving objects moving on the background image are separated from input digital video signal. The separated background plane data and each motion plane data are stored individually in memories 23BG and 23A1 through 23An. Change data on the still images stored as the motion plane data is detected based on the input digital video signal and output of the memories 23BG and 23A1 through 23An to compress and code it by a coding means 26. Still image data of the plurality of plane data of the memory means 23BG and 23A1 through 23An and the change information from the coding means 26 are transmitted.
